According to the Boston Globe, relying on police sources, members of the State Police Special Tactical Operations Team (STOP), a paramilitarized SWAT-style unit, shot and killed Navarette around 5:00am as they tried to search his apartment. When troopers entered the apartment, He "pointed an assault rifle at them and refused commands to submit," said State Police spokesman David Procopio. "A trooper or troopers discharged service weapons in response and struck the suspect."

Navarette was given first aid at the scene, but was later pronounced dead at a local hospital. A 25-year-old woman who also lived in the apartment "suffered an eye injury" during the incident, the Globe noted without further elaboration.

Procopio did not reveal whether it was a "no-knock" search, where police make forcible entry with little or no notice, but he did say the STOP team was deployed because "detectives had direct and credible intelligence that the suspect had indicated that he had firearms and would use them," Procopio said.

The two-story Mechanic Street property where the apartment was located has been on the radar of police for some time. In November 2011, a resident shot another man with a handgun hidden in the apartment. In May, police raided the building, seizing heroin, a scale, packaging materials, and five shotguns, and arresting the building manager.

The use of deadly force by state troopers is under investigation by Northwestern District Attorney David E. Sullivan.

According to the West Virginia Gazette, State Police spokesman Sgt. Michael Baylous said officers from the State Police special response team and DEA agents knocked on the door of Kohler's home at 6:05am. to serve a federal warrant. The newspaper described the special response team as "akin to a SWAT team."

Officers knocked on the door, Baylous said, but no one answered, so police "had to break down the door or forcefully open it somehow." Baylous gave no indication of the amount of time that elapsed between the initial knock on the door and police breaking it open.

When police break down the door, they saw Kohler pointing a rifle at them, Baylous said. The troopers opened fire, shooting multiple rounds and killing Kohler. Baylous said he did not think Kohler had fired his weapon, but it was still unclear.

Baylous said the warrant police were executing was part of a larger, ongoing drug investigation with multiple suspects. He would not comment further on the nature of the investigation, except to say that the DEA division involved was one that focused primarily on prescription drugs.

A neighbor told WSAZ TV that she had seen unusual amounts of traffic going to and from Kohler's home, but that she was surprised to hear he even had a gun.

"I mean, I can't see him just open fire like that, but you know when all that comes after you, you never know what somebody's going to do," Christina Murdock said.

According to reports from WSOC-TV and WBTV 3, police set up a marijuana buy between an undercover police officer, an informant, and two teenagers last Tuesday afternoon. Police said that during the drug deal, Walker pulled a gun and shot the informant in the shoulder in an attempt to rob him.

The undercover police officer then shot Walker in the head, killing him. The teen who accompanied Walker fled, but was arrested later.

"You know, you have 15, 16 year old kids out here wielding firearms, that's a very dangerous situation," said Charlotte-Mecklenburg Police Chief Rodney Monroe, who also defended the decision to do the deal in an elementary school parking lot. "Anytime you conduct an undercover operation, what's a good location? Whether it's a shopping mall or neighborhood, there is no real perfect location."

Monroe also said that school was out and that the site was chosen by Walker and his companion. "This was a location identified by individuals that we were seeking to purchase drugs from," he said. "We were aware that the school was empty of kids."

But residents of the neighborhood where the shooting took place were not mollified.

"It bothers me that I live right across from the school, and it is bad that it was on school grounds," said neighbor Wilmer Bourne. "That's what bothers me so much."

"It's been quiet in this neighborhood, ain't nothing happened over here, everything been good, it's always somebody come in the neighborhood and do this, it ain't nobody in our neighborhood," said resident Johnny Crank.

According to the New York Daily News, citing police sources, officers spotted Muniz conducting a drug deal, and Muniz took off, ducking into a nearby bodega and attempting to swallow a bag of cocaine.

"We believe (Muniz) took a golf ball-sized packet of cocaine and put it into his mouth," said NYPD Commissioner Raymond Kelly. "There was a struggle. When you look at the video, there were no blows struck. There was wrestling, if you will, and also pepper spray was used."

Police said they pepper-sprayed Muniz during the struggle, and he began choking and having difficulty breathing. Police and an EMS crew attempted to revive him at the scene, then the EMS crew took off with Muniz in an ambulance, where they pulled the bag of cocaine from his throat. It was too late; Muniz was pronounced dead upon arrival at North Central Bronx Hospital.

Police were quick to release Muniz' arrest record, which included 23 arrests, mostly for drugs, but also for burglary and grand larceny. He also had nine sealed arrests, mostly for drugs.

According to WLS-TV and the Chicago Sun-Times, both citing police sources, officers tried to stop the vehicle in which Johnson was a passenger, and he jumped out and fled. The officers chased him into an alley in their vehicle, where they saw him slip and fall to the ground. They got out of their vehicle and approached him, with Johnson grabbing his weapon as he tried to stand. One officer fired his own weapon, fatally wounding Johnson.

"As he's running, he's got a gun in his belt, in his back. As he goes to the ground, he's falling and reaching for the gun at the same time. At that point, the officers open fire. I believe the offender is DOA," said Fraternal Order of Police's Pat Camden.

Police say they found a weapon at the scene. Johnson's family disputes the police version of events, according to DNA Info Chicago. Family members said police recovered no weapon and Johnson was shot three times in the back.

Johnson, who had arrests for cocaine dealing in 2008 and marijuana possession in 2011 and had spent time in jail, was uncomfortable around police, family members said.

"They shot my son for no reason," Liberty Johnson said. "He panicked because he doesn't like police. He gets out of the car and runs. You automatically think just because he’s black, he has a gun on him?"

According to the San Francisco Chronicle, citing police sources, Concord police had a warrant for Burns' arrest for drug sales and were conducting surveillance on his Antioch home Friday evening when Burns came out of his home and got into a truck driven by another man.

As detectives "tried to contact" Burns, the driver of the truck "accelerated rapidly and rammed an occupied police vehicle," according to Concord Police Lt. Steve Dyer. Burns then ran from the truck. "Two officers, fearing for their safety, fired at the suspect, striking him," Dyer said.

Burns died at the scene. Police did not mention recovering any weapons, and since Burns had left the vehicle and was fleeing the scene, it is unclear why the officers claimed they feared for their safety. It is also unclear whether police were in uniform or plain clothes.

Perhaps answers will be forthcoming, if not from Antioch and Concord police investigations, possibly from a Contra Costa County district attorney's office review or a coroner's inquest.

Burns' father, a grief-stricken John Burns wasn't waiting for investigations. Police did not have to kill his son, who would have turned 22 on Mothers' Day, he told the Chronicle.

"They should be in prison," the elder Burns said through sobs and expletives, referring to the officers who opened fire. "I wish I knew what happened."

According to Baton Rouge's Fox 44 TV, citing Baton Rouge police, Baton Rouge narcotics detectives went to a Flag Street address to serve a search warrant. The police reported that "detectives noticed the subject was in distress and called for EMS."

Robinson was transported to a local hospital, where he was later pronounced dead.

Police said they believed he had swallowed crack cocaine.

The East Baton Rouge Parish Sheriff's Office was contacted, and detectives from that office will investigate the death. But police said no foul play is suspected and detectives are awaiting autopsy results.

According to local media reports, members of the Warrensburg Police Department's Special Emergency Response Team (SERT) went to Appleton's home to serve a drug search warrant. He "apparently" fired a shotgun at the SERT team as its members entered the residence. Police then opened fire, killing Appleton.

No further details on the shooting were available. Police have not said whether any officers were injured in the incident.

Police said they seized drugs, drug paraphernalia, and firearms, but have not released more specific information.

While the extent of Appleton's criminal history isn't clear, records show he was arrested for drunk driving in Illinois in 2011 and again for driving without a drivers' license in Missouri in February.

The Missouri State Highway Patrol is investigating the shooting at the request of the Warrensburg Police.

According to the Dallas Morning News, citing Richardson police spokesperson Sgt. Kevin Perlich, an officer "was attempting to get a violator to pull over in a parking lot" for reasons that are yet unclear, but Krumrei fled in her Lexus. Shortly thereafter, an officer in a squad car saw her and attempted to stop her, but she refused to pull over.

Krumrei turned onto the southbound frontage road to the North Central Expressway. There, Perlich said, "a third officer near the frontage road was working a traffic accident. He stepped out into the road and tried to get her to stop." But instead, Perlich said, Krumrei accelerated and clipped the officer. "The officer, in fear for his life, fired upon the vehicle," Perlich said.

The Dallas NBC affiliate had a slightly, but significantly, different chronology of the shooting. According to NBC, the officer "fired at least one shot at the woman before being struck by the car."

In either case, the officer was not seriously injured or hospitalized.

Krumrei was taken to a local hospital, where she was pronounced dead. Perlich said an investigation into her death was ongoing, but "it's possible she wasn't stopping because she had several outstanding warrants for her arrests."

The Morning News reported that records show Krumrei had been indicted in Dallas County in April for possessing between one and four grams of cocaine, and that she also had outstanding felony drug warrants from Smith County, a hundred miles to the east.

According to KRQE TV, citing police sources, agents with the Pecos Valley Drug Task Force went to arrest Davis on a felony drug warrant at the Motel 6 in Carlsbad. But "an altercation broke out when agents tried to arrest Davis, and he was shot twice."

He was transported to the Carlsbad hospital, where he died.

The initial reports made no mention of Davis being armed, nor did they provide any further information about the circumstances of his death.

The names of the police shooter or shooters have not been released. The killing is being investigated by the New Mexico State Police.
